Tolls are now $5 each way, if you use the turnpike all the way to Wildwood (exit 304). Only $3.75 if you exit for US27. But that forces a long drive up US27 through Leesburg, etc.
Lots of folks report that they rent a one-way from Enterprise. Apparently, that is less expensive than The Villages shuttle. I've taken to driving my own car o Orlando when I have to fly out of the state, unless I expect to be gone more than 10 days.
